One Monday morning the Mailman is walking through the 
neighborhood on his usual route delivering the mail.
 
As he approaches one of the homes, he noticed that both cars 
were still in the driveway.
 
His wonder was cut short by Derek, the homeowner, coming out 
with a load of empty beer and liquor bottles for the recycling bin.
 
'Wow, Derek, looks like you guys had one hell of a party last 
night,' the Mailman comments.
 
Derek, in obvious pain, replies 'Actually we had it Saturday 
night. This is the first time I have felt like moving since 4:00 PM Sunday. 
 
We had about 15 couples from around the neighborhood over for 
some weekend fun and it got a bit wild. We all got so drunk around midnight 
that we started playing " WHO AM I?"
 
The Mailman thinks a moment and says, 'How do you play WHO AM I?'
 
'Well, all the guys go in the bedroom and we come out one at a 
time with a sheet covering us, with only our family jewels showing through a 
hole in the sheet. Then the women try to guess who it is.'
 
The Mailman laughs and says, 'Sounds like fun, I'm sorry I 
missed it.'
 
'Probably a good thing you did,' Derek responded. 'Your name 
came up 7 times.
